The zero-energy universe hypothesis proposes that the total amount of energy in the universe is exactly zero: its amount of positive energy in the form of matter is exactly canceled out by its negative energy in the form of gravity. Some physicists, such as Lawrence Krauss, Stephen Hawking or Alexander Vilenkin, call or called this state "a universe from nothingness", although the zero-energy universe model requires both a matter field with positive energy and a gravitational field with negative energy to exist. The hypothesis is broadly discussed in popular sources. Other cancellation examples include the expected symmetric prevalence of right and left handed angular momenta of objects ("spin" in the common sense), the observed flatness of the universe, the equal prevalence of positive an

  • Zero energiadun unibertsoaren teoriaren arabera, unibertsoan dagoen energia kantitate zehatza zero da zehazki.

  • El Universo de Energía Cero es una hipótesis que se basa en que la energía total del universo es cero. Cuando la energía del universo es considerada como un pseudotensor, el resultado del cálculo completo es cero. De esta manera la energía positiva en forma de materia se anularía completamente con la energía gravitatoria generada por esta.​​ Al ser la energía total del universo cero, este puede duplicar la cantidad de energía de materia positiva y de energía gravitatoria negativa sin que se viole la conservación de la energía.​ (es)
  • L'universo a energia totale nulla è una teoria cosmologica fondata sull'ipotesi che l'energia totale dell'universo sia esattamente zero: l’energia positiva dovuta alla materia sarebbe cancellata esattamente dalla energia negativa gravitazionale. Tale ipotesi ha consentito a di proporre nel 1973 in un articolo su Nature che l'intero universo sia emerso da una particolare fluttuazione del vuoto quantistico, caratterizzata da una condizione di zero energia che si sarebbe mantenuta nell'universo attuale.
